Hoʻolauna: Nā Holoholona me ka Lapa momona ma lalo o ka huluhulu
He papa momona ka nui o nā holoholona ma lalo o ko lākou hulu a ʻili paha, e lawelawe ana i nā kumu like ʻole. ʻO kēia papa momona, ʻike ʻia hoʻi ʻo ka blubber, kōkua i nā holoholona e mālama i ko lākou kino kino, mālama i ka ikehu, a ola i nā wahi paʻakikī. Loaʻa i nā holoholona ʻokoʻa ka nui o ka momona a hoʻohana ʻia ma nā ʻano like ʻole, ma muli o ko lākou pono a me nā wahi noho.
Ke kumu o ka Lapa Momona ma lalo o ka huluhulu
ʻO ke kumu nui o ka papa momona ma lalo o ka huluhulu e hāʻawi i ka insulation no ka holoholona. ʻO kēia papa momona e kōkua i ka mālama ʻana i ka mahana o ka holoholona ma o ka pale ʻana i ka wela mai ke kino. He mea mālama ia i ka ikehu, e hiki ai i ka holoholona ke ola no ka manawa lōʻihi me ka ʻole o ka ʻai. I kekahi mau hihia, hāʻawi pū ka papa momona ma lalo o ka hulu i ka buoyancy no nā holoholona wai, e ʻae iā lākou e lana a ʻauʻau maikaʻi.
Ka mea nui o ka hoʻokaʻawale ʻana no nā holoholona
He mea nui ka insulation no nā holoholona e ola ai i nā wahi anuanu, e like me ka Arctic a i ʻole Antarctic. Me ka ʻole o ka hoʻokaʻawale ʻana, e nalowale koke nā holoholona i ka wela a hiki ʻole ke mālama i ka mahana o ke kino. Hiki i kēia ke hopena i ka hypothermia, frostbite, a i ʻole ka make. ʻO ka momona momona ma lalo o ka huluhulu kekahi o nā ʻano insulation maikaʻi loa, no ka mea he māmā, maʻalahi, a hāʻawi i ka pale wela maikaʻi loa.
Nā Holoholona Arctic me ka ʻāpana momona ma lalo o ka huluhulu
ʻO nā holoholona Arctic, e like me ka polar bear, walruses, a me nā sila, he papa mānoanoa o ka blubber ma lalo o ko lākou hulu e kōkua iā lākou e ola i ke anuanu a me ka hau hau o ka Arctic. Hiki i kēia papa momona ke piʻi i ka 11.5 knm mānoanoa i kekahi mau ʻano a hāʻawi i ka pale ʻana i ke anuanu loa. He kumu ia o ka ikehu, e hiki ai i keia mau holoholona ke ola no ka manawa loihi me ka ai ole.
Papa Momona ma lalo o ka huluhulu a me ka moe moe
Ke hoʻohana nei kekahi mau holoholona, e like me ka bea a me nā squirrels lepo, i kā lākou momona momona ma lalo o ka hulu e ola ai i nā wā o ka hibernation. I ka wā o ka hibernation, komo kēia mau holoholona i kahi kūlana o ka metabolism haʻahaʻa a me ka mahana o ke kino, e hiki ai iā lākou ke mālama i ka ikehu a ola i kā lākou mau momona momona. ʻO ka momona momona ma lalo o ka hulu e hāʻawi i ka insulation a me kahi kumu o ka ikehu no kēia mau holoholona, e hiki ai iā lākou ke ola no nā mahina me ka ʻole o ka meaʻai.
Nā Holoholona Wai me ka Lapa momona ma lalo o ka ʻili
ʻO nā holoholona wai, e like me nā koholā, nā iʻa, a me nā sila, loaʻa iā lākou kahi papa o ka ʻili ma lalo o ko lākou ʻili e kōkua iā lākou e ola i ke kai anuanu o ke kai. Hāʻawi kēia ʻāpana momona i ka insulation a me ka buoyancy, e ʻae i kēia mau holoholona e ʻau a luʻu maikaʻi loa. He kumu ia o ka ikehu, e hiki ai ia lakou ke ola no ka manawa loihi me ka ai ole.
Holoholona ʻĀina me ka ʻili momona ma lalo o ka ʻili
Loaʻa i nā holoholona ʻāina, e like me nā kāmelo a me nā ʻelepani, kahi momona momona ma lalo o ko lākou ʻili e kōkua iā lākou e ola i ko lākou kaiapuni. Hoʻohana nā kāmelo i kā lākou mau momona e ola ai i nā wao nahele wela a maloʻo o ʻApelika a me ʻAsia, ʻoiai e hoʻohana nā elepani i kā lākou mau momona e ola ai i nā wā maloʻo. Hāʻawi pū ka papa momona ma lalo o ka ʻili i ka insulation a me kahi kumu o ka ikehu no kēia mau holoholona, e hiki ai iā lākou ke ola ma nā wahi paʻakikī.
Hoʻohana kanaka i ka Layer Fat Under Fur
Ua loaʻa pū i nā kānaka nā ala e hoʻohana ai i ka papa momona ma lalo o ka hulu no kā lākou hana ponoʻī. No ka laʻana, hoʻohana ka poʻe Inuit o ka Arctic i ka sila a me ka blubber whale i kumu meaʻai a me ka wahie. Hoʻohana pū lākou i ka blubber e hana i nā lole ʻaʻahu wai a me ka insulation no ko lākou mau home. Eia kekahi, ke aʻo nei nā ʻepekema i nā waiwai o ka blubber e hana i nā mea hou no ka insulation a me ka mālama ʻana i ka ikehu.
Evolutionary Significance of Fat Layer Under Fur
ʻO ka uluʻana o ka momona momona ma lalo o ka hulu he mea nui i ka uluʻana o nā holoholona. Ua ʻae iā lākou e ola i nā ʻano like ʻole a hoʻololi i nā kūlana hoʻololi. ʻO ka mānoanoa a me ka hāʻawi ʻana o ka papa momona ma lalo o ka hulu he ʻokoʻa i waena o nā ʻano ʻano like ʻole, e hōʻike ana i ko lākou mau pono kūikawā a me nā hoʻololi.
Lapa momona ma lalo o ka huluhulu a me ka hoʻololi ʻana i ke aniau
He hopena koʻikoʻi ka hoʻololi ʻana i ke aniau i nā holoholona me ka momona momona ma lalo o ka hulu. Ke piʻi aʻe ka mahana a heheʻe ka hau, ke kū nei nā holoholona Arctic i nā pilikia hou i ka ʻimi ʻana i ka meaʻai a me ka mālama ʻana i ka mahana o ko lākou kino. Ke ʻike nei kekahi mau ʻano, e like me ka polar bear, i ka emi ʻana o ka heluna kanaka ma muli o ka nalowale o ko lākou wahi noho maoli. ʻO ka hoʻomaopopo ʻana i nā hopena o ka hoʻololi ʻana i ke aniau ma luna o nā holoholona me kahi ʻāpana momona ma lalo o ka hulu he mea nui ia no ka mālama ʻana a me ke ola ʻana.
Ka Hopena: Nā Kupanaha o ka Lapa momona o nā holoholona ma lalo o ka huluhulu
ʻO ka momona momona ma lalo o ka hulu he mea hoʻololi kupaianaha i hiki i nā holoholona ke ola i nā ʻano like ʻole. Hāʻawi ia i ka insulation, mālama i ka ikehu, a me ka buoyancy, e ʻae ana i nā holoholona e ulu i nā kūlana paʻakikī. Ke hoʻomau nei mākou e aʻo hou e pili ana i nā waiwai o ka blubber, e ʻike paha mākou i nā noi hou no kēia mea kupanaha. ʻO ka hoʻomaopopo ʻana i ke koʻikoʻi o ka papa momona ma lalo o ka hulu he mea nui ia no ka mālama ʻana a me ka pale ʻana i kēia mau holoholona kupanaha.
